Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619366, here are decompositions:

7 + 31619359 = 31619366
109 + 31619257 = 31619366
157 + 31619209 = 31619366
223 + 31619143 = 31619366
349 + 31619017 = 31619366
367 + 31618999 = 31619366
487 + 31618879 = 31619366
547 + 31618819 = 31619366

Showing the first eight; more decompositions exist.
